We currently have a client that has a 7970 phone that's attached to a 871W using ezVPN to establish the VPN connection back to the Call Manager. He wants to move from Time Warner Cable to AT&T's U-verse.
The questions are:
1. Can this setup work with AT&T's U-verse. I don't know much about it.
2. If so will I need to reconfigure how the 871W establish's the VPN connection?
Below are the configurations on the 871 that matters:
------------------------------------------------------------------------------------------------------------------------------
crypto ipsec client ezvpn **VPN Name**
connect auto
group **VPN Name**Group1 key **KEY**
mode client
peer **IP Address**
acl 100
username **Username** password **Password**
xauth userid mode local
interface FastEthernet4
ip address dhcp
no ip redirects
no ip unreachables
no ip proxy-arp
ip flow ingress
ip nat outside
ip virtual-reassembly
no ip route-cache cef
duplex auto
speed auto
no cdp enable
crypto ipsec client ezvpn **VPN Name**
interface BVI2
description ***VPN Name**-VOIP-Interface*
ip address 10.10.11.1 255.255.255.0
no ip redirects
no ip unreachables
no ip proxy-arp
ip flow ingress
ip nat inside
ip virtual-reassembly
crypto ipsec client ezvpn **VPN Name** inside
------------------------------------------------------------------------------------------------------------------------------------
Thanks in advance for any assistance.

I don't think you have to reconfigure anything. This is not (fortunately) phone proxy.
Sometime on dynamic address routers, it's useful to configure DDNS, so from outside, you know always "where" are they.

Yah I probably should have said remote phone instead of proxy phone. In the past we had performance issues using DSL with this setup. So we have been careful to make sure that the VPN connection is through cable.

I have many, many remote phones all over the world using all kinds of access technologies (and no I'm not Skype).
All do work great
Thanks for the nice rating, and good luck!
